Issue date:        2010-07-28
CVE Names:         CVE-2010-2526
Description:

It was discovered that the cluster logical volume manager daemon (clvmd)
did not verify the credentials of clients connecting to its control UNIX
abstract socket, allowing local, unprivileged users to send control
commands that were intended to only be available to the privileged root
user. This could allow a local, unprivileged user to cause clvmd to exit,
or request clvmd to activate, deactivate, or reload any logical volume on
the local system or another system in the cluster. (CVE-2010-2526)

Note: This update changes clvmd to use a pathname-based socket rather than
an abstract socket. As such, the lvm2 update 2010:0569, which changes
LVM to also use this pathname-based socket, must also be installed for LVM
to be able to communicate with the updated clvmd.

All lvm2-cluster users should upgrade to this updated package, which
contains a backported patch to correct this issue. After installing the
updated package, clvmd must be restarted for the update to take effect.
